Research Summary

We study how vitamin D, via the vitamin D receptor (VDR), decelerates chronic diseases of aging, such as osteoporosis and neurodegeneration. We hypothesize that 1,25-dihydroxyvitamin D (1,25D), through regulation of a novel bone-initiated FGF23/klotho/phosphate/CYP24A1 axis, prevents hyperphosphatemia and excessive concentrations of 1,25D, thereby slowing the onset of ectopic calcification, fibrosis, and vascular disease that can lead to kidney failure, myocardial infarction, and ischemic stroke.
